“...but I need to change the diet to where I’m on one forever.”
Welcome to the club... my body is becoming resistant to insulin.
I now eat a diabetic diet, which really is pretty good eating. I just had to cut out simple carbs and learn to be judicious with some complex carbs. No snacks. Lots of vegetables, mostly greens, no juices but whole fruit in moderation is okay.
There is a boatload of literature out there. Dr. Fuhrman has put out some good resources and recipes.
Thanks for the info and I hope you are okay
